Concept Search - What can I type?

For a concept search, you can enter phrases, sentences, or full paragraphs in English. For example, copy and paste the abstract of a patent application or paragraphs from an article.

Concept search eliminates the need for complex Boolean syntax to inform retrieval. Our Semantic Gist engine uses advanced cognitive semantic analysis to extract the meaning of data. This reduces the chances of missing valuable information, that may result from traditional keyword searching.

Abstract

The misalignment of a document and the lack of orthogonality of a linear CCD with respect to the document transport direction causes skewness and geometric distortion, respectively, in the scanned image. While the conventional techniques help eliminate the skewness due to the former cause, the effects of the latter cause remain uncorrected.

This text was extracted from an ASCII text file.

This is the abbreviated version, containing approximately
100% of the total text.

The
misalignment of a document and the lack of orthogonality of
a linear CCD with respect to the document transport direction causes
skewness and geometric distortion, respectively, in the scanned
image. While the conventional techniques
help eliminate the skewness
due to the former cause, the effects of the latter cause remain
uncorrected.

Both of these
errors are corrected by exercising the algorithms
during image extraction, from the stored uncorrected image.

The first
error (document skew) is accomodated for by measuring
the document skew with respect to the x-axis (Figure) and then
extracting the image from the rasterized image buffer. It is shown
as dots along the document edge.

The process
continues, as each of the rasterized image lines
(parallel to X-axis) is extracted. The
same skew angle is used for
correcting errors along the Y-axis.

The second
error, leading to geometric distortion of the image,
is fixed for a given set of hardware.
While deskewing the image, as
illustrated above, the skew angle along the Y-axis is modified by
this error, i.e., the skew angle is modified by the measure of
misorthognality (fixed for a system ).
